Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention is to attach a substantially L-shaped concrete panel forming a corner portion such as an outer wall or a partition of a building to a building frame efficiently and without deteriorating aesthetic appearance. The present invention relates to a structure for mounting a concrete panel having a substantially L-shaped cross section, which enables the above.

<Conventional technology> Conventionally, when this kind of approximately L-shaped concrete panel is attached to a building frame at a construction site, for example,
As shown in FIG. 5 and FIG. 5, counterbore holes 2 penetrating from the front surface to the back surface are formed on both sides of the substantially L-shaped concrete panel 1, and bolts 3, washers 4 and nuts 5 are used.
The L-shaped plate 6 is attached to a corner portion of the substantially L-shaped concrete panel 1, and the L-shaped plate 6 is fixed to a steel receiving material 8 such as a piece angle material previously fixed to a pillar 7 of a building. The L-shaped concrete panel 1 was attached to the building frame.

<Problems to be Solved by the Invention> However, in the above-described conventional technology, the substantially L-shaped section concrete panel 1 must be provided with the counterbore 2 penetrating from the front side to the back side. There is a problem that the front side of the section concrete panel 1 is damaged, and the work of repairing the counterboring hole 2 is required after the substantially L-shaped section concrete panel 1 is attached.

In particular, when the substantially L-shaped concrete panel 1 is a design panel or the like having an uneven pattern on its surface, it is extremely difficult to finish the repaired part in the previous state, and the repair material used in the repair is used. Depending on the method of preparation of No. 9, the quality of the repaired state, etc., there is a problem that uneven color or unevenness remains in the repaired portion after the construction or a crack is generated in the repaired portion.

Further, in the above-mentioned conventional technique, bolt 3, washer 4,
Since a large number of small metal parts such as the nuts 5 are used, there is also a problem that work efficiency is poor.

The present invention relates to a completely new technique developed in view of the above conventional problems.

<Means for Solving the Problems> The present invention is a technology that fundamentally improves the above-mentioned conventional problems, and its gist is a structure in which a substantially L-shaped concrete panel is attached to a receiving steel material fixed to a building frame. In the above, the bar-shaped steel material of the T-shaped mounting bracket provided with a plate portion at one end of the bar-shaped steel material is inserted into a small hole formed in a long side small hole of the substantially L-shaped concrete panel, and the T-shaped mounting member is provided. The plate part of the metal fitting is fixed to the receiving steel material.

<Operation> In the present invention, as described above, a small hole is formed in the long side of the substantially L-shaped concrete panel, and the bar-shaped steel material of the T-shaped mounting bracket is inserted into the small hole. ,
There is no need to drill a counterbored hole that penetrates the front and back surfaces of the substantially L-shaped concrete panel.

Therefore, the repair work of the counterbored hole can be made unnecessary.

<Embodiment> Referring to the drawings, a substantially L-shaped concrete panel mounting structure according to the present invention will be described. FIG. 1 is a perspective explanatory view showing a main part of the mounting structure of the present invention, FIG. 3 (A) and (B) are explanatory diagrams of a T-shaped mounting bracket.

1 to 3 (A) and (B), 10 is substantially L
The concrete panel 11 is a pillar of the building, and a receiving steel material 12 made of a piece angle material is fixed to a predetermined position on the outer surface thereof.

In addition, as is apparent from FIG. 2, a small hole 13 into which a bar-shaped steel material described later can be inserted is formed in the long side small edge of the substantially L-shaped concrete panel 10. Reference numeral 14 denotes a T-shaped mounting bracket, which has a structure in which a disk-shaped plate portion 16 is provided at one end of a bar-shaped steel material 15 as apparent from FIGS. 3 (A) and 3 (B). Are formed with four projections 17 at a predetermined interval.

Substantially L-shaped concrete panel 10 used in the present invention
The length of the short sides perpendicular to each other is about 150 to 600 mm per side. As is apparent from FIGS. A total of four small holes 13 having a depth of about 200 mm and an inner diameter of about 10 to 20 mm are formed vertically.

The outer diameter of the bar-shaped steel material 15 of the T-shaped mounting bracket 14 is
13 is formed with a diameter substantially equal to or slightly smaller than the inner diameter of the thirteenth. Accordingly, when the bar-shaped steel material 15 is inserted into the small hole 13, the projection 17 protruding from the bar-shaped steel material 15 bites into the inner peripheral wall surface of the small hole 13, and the T-shaped mounting bracket 14 becomes substantially L-shaped during the construction work. It prevents falling off from the concrete section panel 10.

The small hole 13 may be drilled at the factory when the substantially L-shaped concrete panel 10 is manufactured, or may be drilled at the construction site.

In the construction of the mounting structure according to the present invention, at the construction site, a T-shaped mounting bracket 14 is inserted in advance into each of the small holes 13 and attached to the substantially L-shaped concrete panel 10, and then the substantially L-shaped concrete The panel 10 is erected at a predetermined position on the pillar 11 of the skeleton, and the substantially L-shaped concrete panel 10 is welded by welding the disc-shaped plate portion 16 of the T-shaped mounting bracket 14 to the receiving steel material 12 previously fixed to the pillar 11. By attaching and fixing to the column 11, the whole can be assembled and configured.

<Effect of the Invention> Since the mounting structure of the substantially L-shaped concrete panel according to the present invention has the above-described structure and operation, it is not necessary to form a counterboring hole in the substantially L-shaped concrete panel as in the related art. Therefore, there is no need to worry about scratching the surface of the approximately L-shaped concrete panel, and it is possible to eliminate the need for any work for repairing the counterbored hole, thereby reducing the design of the panel surface, uneven color due to poor repair, and unevenness. All problems such as generation of a surface or a crack can be solved.

In addition, when a substantially L-shaped concrete panel is mounted on a skeleton, only one type of T-shaped mounting bracket is required, and a large number of conventional mounting brackets such as bolts, nuts, and washers can be eliminated. Is remarkably improved.
